Typox

AI-powered grammar and spelling correction app. Built with Tauri.

Select text anywhere, trigger the global shortcut, and Typox corrects it in place — spelling, capitalization, verb forms, and obvious contextual errors — without changing your tone or style.

Features

• Works everywhere — captures selected text from any application
• Multiple AI backends — Ollama (local/private), Claude (Anthropic), OpenAI
• Floating diff widget — shows exactly what changed before you apply
• Editable corrections — tweak the AI result before applying
• Customizable shortcut — change the global trigger from Settings
• Auto-updates — checks for new versions at startup
• Launch at login — runs silently in the menu bar
